Specification of Letters Patent.

Patented Jan. 1s, 1910.

Application filled March 3, 1908. Serial No. 418,998.

To all whom 'it may concern:

Be it known that I, SIMON W. WARDWELL, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements inv Winding-Machines, of which the following is a specification. e

My invention is a Winding machine Afor producing bodies of textile or other attenu ated material, of a form suitable for use in Afabric forming processes, and especiallyfor l density, and which, by its peculiar yarn disposition shall permit the yarn mass to completely fill the -yarn space in the shuttle, laterally touchingl its sides, and yet deliver all its substance without restriction orbreak until said substance is entirely exhausted, without residue.

The mechanism whereby the foregoing is accomplished is fully disclosed in the following specification and accompanying draw-- ings, which latter' show respectively:

Thelnachifne consists of a .plurality of winding heads, each comprising preferably, one or 'more pairs ofopposed winding spring detail of the member 56. Figs.-

spindles, with their attendant winding mechanisms, and one driving head which contains the elements that actua-1e the mechanisms of the connected pluralityof winding heads.

In Fig. 1 and Fig. 2, A is the case of the winding head in which are bearings 2--2 for the Winding spindle 3, and a socket 4 for the bearing of the traverse rbar 5. winding spindle 3 is driven with the spiral gear 6 by means that will be'described later.

The traverse bar 5'is capable of longitudinal reciprocation inthe quill or sleeve bearing 7 that is held in the socket 4, and in an outboard bearinur 8 which is secured to or forms a part of the projecting bracket 9. The traverse bar carries a thread' guidev arm 1() in which is a thread guide 11. The' traverse bar. with its thread guide arm and The guide, .is connected by a'link l2 With the traverse arm 13 on the rock-shaft 14 whose mode of operation will be later described in connection with the driving head.

The portion of the traverse bar 5 opposed to the winding spindle 3, is formed with an eccentric screw thread, of such degree of eccentricity that there is a full thread on the side or surface toward the winding spindle, but no thread whatever on the surface which. is away from the winding spindle, as indicated in Fig. 2 and more clearly'shown4 in Fig. 7, where' 15 indicates the screwl threaded surface of the traverse bar 5. Engaging this eccentric screw is a nut 16 which is pressed toward the traverse rod 5 by the 4 Obviously, when the thread guide arm 10 is in a position such as shown in Fig. 7, the spring17 presses the nut 16 into engagement with the screw thread 15, and any rotation of the nut will cause the thread guide arm4 10 to travel on the traverse bar. Such progressive travel is effected by the thread guide traveling mechanism, detailed in Fig. 10 andFig. 11, and 'further indicated with other coadjuncts in Figs. 1, 2v and 7.

The nut 16 is of internal diameter' and thread corresponding with the eccentrically threaded portionof the traverse bar 5', and consequently of larger diameter internally than is the traverse bar 5 externally.' It has a flange 18, preferably about midwayl of its ends, which supports a contact wheel or flanged disk 19. 'This disk 19 is dogged o`r rotatively connected'withthe nut b v-the pin 2() by the cupped washer 21, held in place by the clip 22 Awhich is snapped into a groove in the nut 16. The latter is hel'd on the traverse bar between the two legs or branches of the bifurcated thread guide arm 10 and, as previously explained, is heldy against the traverse bar by the spring 17. This is secured' in the thread guide arm 10, by the thread guide 11, the two` interlocking, each securing the other. 5 y

The thread guide arm isformed (Fig. 6) witha flange 10El which extends across the extremity of the arm and along one side.- At the extremity of this arm is a recess 23 of substantially T form.- Directly behind the recessed extremity is a seat for the thread guide 11. The latter is formed with shoulders 11a to abut the bottom of the thread guide arm and grooves 11b just above the top of same, and it is obvious that any element engagingthese grooves will act as va lock or latch to `draw thev shoulder 11a -against the threadguide arm 10 and lock spring wire of substantially hair pin shape,

i but with one prong longer than the other to'act on the nut 16. The two prongs, 178l and 17, pass to either side of the thread guide 11, through laterals 23a and 23? of the T recess 23, (Fig. 2) projecting the loop 17 c of the hair in beyond the extremity ofthe thread guide arm 10. Immediately beyond they extremity of the thread. guide arm, the prongs 17% and 17 b, rise at an angle to the point 17d,- (Fig. 5 and Fig. 7) where the loop 17 -C drops abruptly, spreading, preferably in circular form,(Fig. 1) vto form the auxiliary guide referred to.

The two prongs 17@l and 17b engageithe grooves 11b of the: thread guide 11, thus sethe latter as indicated and the guide 1 1, being interposed between the two prongs 17a and 17"., prevents them from'sprmging together and disengaging from the later'als 23a'and'23b. The portion of 17 which enf,

gages the nut 161is bent in knee' or toggle orm"at 17f,'and inV such directionthat the- `elastic action of holding the nut 16 in place draws ...the spring' 17- tightly against the guide 11 securing the latter more firmly.

The guide 11,.may.'be of any suitable construction, formed as indicated in Figs. -5

and f7 ofsolid material and as indicated in Fig.l 2, with a round body to which thej the crease orthreadway 11 to control the yarn,-and prevent itfrom rolling, thus insurlng posltlve and accurate disposltion. At

the same time the lateral grooves 11b for the wire 17 are formed. This forming is accomplished in smoothlyburnished dies, so that the resultant guide is of smooth surface, devoid of theV roughness and chatter marks incident to machine cuts. The shoulders 11a are preferably machine cut, to secure accuracy of relation .between them and the grooves 11b and insure -interlocking with the wire 17. i Being made of thin steel, the guide can be thoroughly hardened and to a degree that is-attained with great certainty and little liability to cracking, and finally the cost is slight, due to performing' by press in one operation, what would require a multiplicity of, machine cuts.

At one side of the thread guide arm is a bobbin Wound. The bail is preferably of wire having guide portions 25a and 25",

(Figs. 12 and 13) which t and run ingrooves 26 in the bearing bar 27, (Fig. 5) and the depending,' inclined guide portion 25c which engagesthe guide lug aforesaid.

The portions 25d are looped back,..to'avoid and clear the body of the bearing bar 27 (Fig. 5.).-

The bearing bar 2,7,fis a bar which reacts against the thread guide arm, through the bail 25', to counteract the vibration and chatter due to rapid reciprocatiomfrjlts function is to control the inertia the lirrqgl'llarities. of action naturally superinduced by rapid reciprocation and in this case augmented Yby the combination of reciprocation along the winding spindle with oscillation toward and fromythe spindle. To this end, the bearing bar 27 is made of suiicient mass for the purose intended. vBygwo arms 27a and 27b the earing bar is hung on the traverse bar 5.

The action of the Winding mechanism is therefore as follows. Winding is done on a bobbin having a tapered base, substantially as indicated in Fig. 1 by the-brokenlines. At the commencement of winding, the thread guide 11, is directly opposed to the bobbins tapered base, 'the yarn being drawn from a supply of usual form, through tensions 28 and the loop or auxiliary guide 17cf The diameter of the contact Wheel 19 is such that when the base diameter of the taper of the winding attains its prescribed diameter it en gages the said contact wheel, causing a slight rotation and corresponding advance of the guide along the winding -spindle and reducing the winding diameter. .l When the yarn mass again attains its prescribed diameter which .1s the diameter of the bobbinfthe.'

.guideis again similarly advanced, and as itA advances it carries the bail 25, by engagement of the lug 24, with the portion 25,.

During the winding, the draft of the vyarn from the supply, through the tensions .holds the guide 11 in Contact with the winding surface, so that the yarn being wound is completely conned between the surfaceof the bobbin and the walls or sides of the threadway or crease 11; thus controlling the disposition of the yarn accurately. When the bobbin has beenwound to the desired length and the winding hasl stopped, the guide 11 with its guide arm 10 is disconnectedfrom the traverse bar by turning it back from the winding spindle 3, until the spring 17, forces the nut 16 out of engagement with the screw threads of the traverse bar 5. It is then slid on the 'traverse bar back to its starting point. The winding is discontinued by the controlling mechanism which comprises the following instrumentalities. Carried on-the rod 29 is an arm 30 twisted like a propeller blade to present an inclined surface to the hub 10b of the thread guide arm 10, Fig. 2. Pressure of the hub 10b on the arm 30 rocks the latter and with it the rod 29 and an arm 31 on said rod, preferably a formation thereof. (Figs. 1 and 5.)

Fulcrume'd at 34 (Fig. 5) preferably to th bracket 9 is a detent lever 35, having-a detent shoulder 35, which engages a detent 36 to restrain the latter from movement. This detent, as' will be later explained,- controls the clutch of the stop device.

Attached to the detent lever 35 is a pawl 37, which rests on the` arm 31. and has atransverse portion 37a (Fig. 9) adapted to engageprojections 38a on the stop collar 38 which 1s fast on and rotates with. the winding spindle 3, in the direction indicated by the arrow m. Elevation of the pawl 37,

moves its portion 37*L into the path of the projecting loop portion 37b augments the downward tendency of the pawl 38, bothby its intrinsic mass, and by the leverage due tothe projection of that mass ybeyond the bearing' point on the arm 31 and also' providesfor the other automatic actuation as f ollows.- The rod 29 will alsobe automatically rocked to disengage the detent lever and detent by instrumentality of the end stop 39 which is fulcrumed at 40 in the tension bracket 41; n'Ilhe end stop 3 9 is preferably formedf of Wire, having a hub formed .f of a plurality of c'oils from which one portion for-arm of the wire 39a extends up to a pointadjacent the pawl 37 whence it is diverted in direction to incline it to the pawl 1n a Wedgelike relation, and to an extent that insures against disengagement.v

l therefrom. The' other arm 39b of the wire 'and secured.

yarn as it draws from the tensions as is described in my pending application Serial' No. 419,000, filed March 3, 1908.

Rocking'of the rod 29 for the purpose of effecting disengagement of the detent lever and detent has been ascribed to engagement of the thread guide arm hub -10b with the arm 30 and other automatic actions. Obviously the same effect will result from a manual rocking of the arm 30, and this is an intended provision, so the operator may stop the machine at will. j The winding is started by rocking the starting handle 44 in the direction of the arrow a, Fig. 5, thereby moving the detent 36 with which it is connected bythe rod 45, into engagement with the detent lever 35. Preferably, the starting handle 44 is integral with the rod 45, being formed'thereon.

The rod 45 has a bearing 46 in the bracket 9, and a bearing 47 in a stem portion of the a the rock shaft 14 and has for a rotative bearing, a trunnion or pin 49 secured in the case A. The bearing 47 is in a stem of the bracket 9 by which the latter is secured to the case A. The stem projects through a hole or socket suitably formed in said case. The portion which projects into the case is threaded to receive the nut 47EL whereby the bracket 9 is drawn tightlyA against said case The bracket 9 is further secured from turning by the trunnion p in 4 9. which extends through both the case A and the bracket, acting thus as a dowel.

Extending upward from the bridge 48 vis a clutch arm 50 havinga beveled side to engage with-wedging action the beveled flange 51 of the clutch 52. /This clutch is of usual form, preferably 'of the friction type, and is impelled-by the clutch-spring 53 to engage the'skew gear 6 through which the winding spindle 3 is driven. Engagement of the Clutch arm 50 with the clutch flange 51 results in disengagement of the clutch 52 and' 'skew gear, and consequent stopping of the winding spindle.

The clutch arm 50 is impelled to engage the clutch flange 5y a spring 57a that extends from an overhang 55 'of the member 56 of which the quill bearing 7 is a part, to an arm 57 of the bridge member 48, (Figs. 1,2 and 5). Therefore, with the parts immediately described, under the effect of the clutch arm spring j57a there is no operation of vthe winding spindle. By rocking the starting handle 44 as described, the lclutch 52 is permitted* to n engage its skew gear'6' and to be operatively' driven thereby. In like .mannen the same elements. control the operation of vthe trav-'- f verse mechanism, by the following means As previously indicated, the traverse bar lio abutment may be a similar adjoining sleeve of an adjacent traverse mechanism as 1ndicated by the dotted lines of Fig.' 15, or as indicated in Fig. 2, it may be the bearing .70 of the rock shaft. On the face of the bearing 13b is a projection 13c having beveled sides and adjacent thelatter is an upward projection 131 with a beveled face whose function will be later described. Adjacent to the bearing 131. a

block 59 is secured to the rock shaft 14, having in its face a recess 59a having inclined or beveled sides, corresponding 'to those of the projection 13c whlch is normally maintained in engagement with the recess 59a by the spring 58. The tension of this engagement is amply suflicient to drive the traverse mechanism, but affords a yielding condition which safeguards against breakage. f In case of'any obstruction to thel traverse movement, the block 59 and the traverse arm 13 disengjage automatically, arresting the traverse action, even though the rock shaft 14 should continue. to oscil' late.

Attention has been directed to the upward projection 13d.' This lies directly below the U formed portion 48a of the bridge member 48 and, during the operation of the traverse mechanism, oscillates between the sides of the U. Then the rod 29 is rocked to stop the machine, it depresses the U portion 48a of the bridge member 48, see Figs. l and 2 engaging it with the beveled upturned projection 13d, acts asdoes the clutch arm 50 in the clutch 52, withdrawing the traverse arm 13 from engagement with the oscillating block 59,L7and thereby arrests the traverse action. To hold Ithe traverse arm 13 within the range of oscillation of the rock shaft 14 and the block 59, ya retainer or limit is provided, inthe plate 60 which has two ears 6021,60a (-Fig. 17) which extend up from the ends of the plate 60, inward toward its center and down across the path of oscillation of the extremity of the projection 13d. This form imparts a desirable elasticity to yield to blows o-runusual stress. This plate is secured to the bridge member by any suitable means as the screws 61, 61.

'The mode of connecting the traverse-bar with the traverse arm is unique and peculiarlyadigntageous, in that it provides for ease of quick adjustment and is unusually simple, though of substantial'construction.

The traverse bar bearing 7 is in the form of a quill or sleeve forced into a socket 4 in the case A, being one portion of a member 56 which comprises a lateral projection 56a that embraces the winding spindle 3, the latter-acting as a do'wel to keep the piece from turning, as shown in Figs. land 2.

The inward projecting extremity of the member 56 Figs. 1 and 14, has a bearing 561 for the traverse rod, and a dependent leg 56c in which is a guide slot -561 for the traverse link 12 which is attached to the traverse bar by a connecting pin 62. The other end of the link also has a connecting pin 63, preferably made Aby forming the link at right angles. This pin. 63 engages any desired one of a plurality of holes in the traverse arm 13, ,depending on the eX- tent of traverse desired. As the link is guided in the slot 56d and Withheld from lateral movement, it is obviously imprac- 'ticable to interchange the position of the pin 63 on the arm 13, by manipulation of the link. To effect such an interchange, the traverse arm 13 is simply shifted along the rock shaft 14 until disengaged from the pin 63, when the latter is shifted to whatever hole is desired in the traverse arm 13. The driving head is illustrated in Figs. 18

and 19. The case B has bearings. 101 and 102 in which runs the shaft 103, that extends from the driving head through all the winding heads. Within each winding head (Fig. 2) this shaft carries skew gears 101y ythat mesh with the skew gears 6 on the winding spindles3 and whereby the latter are driven.

Outside the case B the shaft 103 carries a clutch pulley 105 which rotates freely on the shaft adjacent the clutch 106- which rotatably, is secured to the shaft but free to slide thereon longitudinally; The means whereby the clutch is thus mounted are as follows z-The clutch hub 10.6a has projections 106b which engage corresponding recesses 107ain'the collar 107 which is lixedly secured to the shaft 103. The extent of this engagement is such that the clutch cannot be disengaged from its collar by any movement within its normal range. Within the collar 107 is a recess 107", and in this recess, between the collar and the end of the drivingv pulley hub, is a s'pring 130 which normally'holds the clutch and pulley in engagement. Disengagement of the clutch 106 and the pulley 10,5 is effected by the handleI 109. In the hub of the clutch is a peripheral Groove 108 which is engaged by the projec- 109 rocks in abearing 110a of the'overhanging bracket 110, which in turn is secured to tion 10S)a of the handle 109. The handle.;

a bevel gear 111 which meshes with the bevel i 25 the traverse mechanism is regulated. The

55 concurrent and coperative action 'of -the fwlnding and traverse mechanism as previgear 112, which, through the train of spur gears 113-114-115-116 rotates the cam 117. The bevel gear 112 is mounted on a stand 125 on the case B. Set in the top of the stand is La pin or stud 126 which is the bea-ring for the gear 112, thelatter having a long hub 112 fitted thereto. The bevel gear 112 is maintained on the stud lby the collar 127 with its set screw 128. On the hub of the bevel gear 112 is secured the gear 113.-

The cam 117 is a cylindricalam, and is connected with the gear 116 by driving pins 118. The gear 116 is mountedV on the hub of the cam 117 and the latter has a running bearing on a quill or sleeve 119 which is held in the case B by the stud 120 and forms the hub of a change gear arm. From the top of the quill there extends laterally an arm 119a With an arcal transverse portion 1191, one end of which has a slot 119c and the other end a stud or bearing 124 for the gear 114, which is a change gear Whereby the ratio'of speed of revolution of the Winding spindles to reciprocating speed of slot in the other end of the arcal portion is for the purpose of securing the gear 114 in mesh with the gear 113.and for permitting an interchange' of gears as indicated. This is effected by the shouldered stud 121 Whose body tits freely the hole or 'socket 121d in the-bottom of the case B. To prevent the stud from turning, `a substantially rectangular portion 121t is formed to enter the slot 119C, from which extends the screw threaded `stem 121b to which is fitted the nut 121. This construction permits the arm 119a to be. securely locked without disturbance of its form or position, which would distort the cam bearing and increase the frictional resistance at that point.

The rock shaft 14 which extends through all the winding heads and on which all the traverse arms 13 are mounted, extends into the driving head near the cam 117, and carries on its end a rocker arm 122, which rcarries, preferably at its extremity, suitable means for engaging the cam groove such as the' roll 123.

Obviously, rotation of the clutch pulley causes, through the train of mechanism just described, concurrent `rotation of the haft 103 and oscillation of the rock sha 14, through which the Winding is effected by further discussion is needless.. It is pointed out however, that the ultimate product of the machine is distinctly novel because of its compactness and itsl Jaction in delivery. "Whereas, the types of bobbin usually employed are subject to repeated breakages and variations of tension, the bobbins Wound by.

this machine are characterized by continuity of delivery and uniformity of tension. This Y construction and arrangement of the parts,
